The Great Thermostat Debate [Merged]

[radiazone]

ano ba suitable spec ng thermostat para sa tropical climate like our country?

is it 71 deg cel, 82 deg cel o 88 deg cel?

sa mga engine nyo anong spec nakalagay?

thanks

Ngayon ko lang nalaman na may temp setting pala ang thermostat.
Kung gayon dapat ang temp setting ng thermostat ay near engine temp at optimum performance. Help!

the 88 deg cel is installed in japanese surplus car, as i research this 88 deg cel is called the winter thermostat and the 82 deg is normal, i have no idea bout the 71 deg

I have a 99 civic, and delayed yung pagikot ng fan.pag lumgpas na sakalahai,saka lang umiikot. munghang thersmostat na yung sira.any idea kung magkano yun saka kung san ok magpagawa?tatagain nanaman ako sa casa pag nagkataon.Taga T.sora ako
thanks

[non-vtec]

there are replacement thermostat for hondas. just look around in banawe or other auto supply shops.

btw, i think there's a spoon sports thermostat. it opens at a lower temp than the stock one.

[blink21me]

IMHO hndi mo kelangang tanggalin yung thermostat, you just have to replace it with a new one... Nung pina pre-purchase inspection ko yung kotse ko they found out the t-stat is faulty 9it's stucked open) that's why it takes time for the before my engine heats up to normal operating temp... I just had to buy one and did it myself, everything went good...

Kaya nga nilagay ng manufacturer yung t-stat don kase kelangan yon, otherwise they would delete it themselves before they sell the car brand new... don't delete it!!!

Sir, hindi kaya yung thermoswitch ng electricfan ang problema?

The thermostat in this thread is the thermostat along the coolant lines that open up as the engine heats up. This thermostat does not control anything else on the vehicle.

[radiazone]

mga masters any idea?

[OTEP]

I just put the OEM one. Hindi ko na din nacheck ang spec. At least better than not having any.

I have a '97 VTEC and also experienced sudden rise in temp to near overheating. I noticed that my radiator fan was not working. I pulled the connector from the thermal switch which controls the fan and put a jumper wire accross. Thus turning the radiator fan always on. From then on I my engine temp is always at normal.

IMHO, there are two thermostat installed in the engine. One is a switch which controls the on/off function of the radiator fan and the other is a sensor which only feeds information to our cars temp gauge.

[OTEP]

We should always be aware that these three parts are different:
-Thermostat for the engine's cooling system (see photo a few in post #44)
-Thermostat for a/c (the one you adjust in the cabin)
-Thermoswitch for triggering fans
-Temp sensor (sends reading to the temp gauge)

Also learned last Saturday that on the Vitara, the coolant temperature sensor reads the coolant temp, sends a message to the ECU and the ECU adjusts idling. When the temp is too low, it will idle at a higher speed to try and bring the temperature to optimal (at the expense of fuel economy). According to the Suzuki tech, almost all modern cars have a similar system. Removing the engine thermostat will just promote fuel wastage.

the rad fan wasn't designed to stay running all the time. my dad had a lancer itlog and when the thermoswitch got busted, he decided to bypass that too and made the rad fan working all the time.

the result: every 6-8 months he had to replace his radiator fan.

the thermostat and thermoswitch are there for a reason. I don't think the car manufacturers would put them there just for kicks, or extra bucks. don't you?

So, if ung car mo walang thermostat that means kelangan mong maglagay???

Yep, yung LC namin walang thermostat nung mabili. Sinuyod pa ang Banawe to find one. 22R yung engine. Nagkasya naman yung pang Toyota Cressida.

[altlance]

need help lang po to sir otep and other gurus here.

my car's temp is usually very low (1/4 lang sa gauge) kapag a/c on.

pag walang a/c the temp is always a little below half. ito dapat yung normal di po ba?

Ano kaya problema?

I notice also that the two fans (one in front of the radiator and the one behind, am not sure what they are called) are running at the same time always. Di po ba dapat ay magkahiwalay ang pag on nun? iyung isa yata dun ay fan na nago-on pag on ang compressor ng aircon.

may kinalaman kaya sa thermostat problem?

car is ae92

[OTEP]

Seems like a thermoswitch problem. Baka naka-rekta na yung fans (always on).

the connector of the aircon could either be tapped or naka rekta
o di kaya natanggal yung thermostat switch located sa may engine.

I like this thread. There is no debate.

If you are told to remove your perfectly working thermostat from
your cooling system.


Take your money and run!

[mark_t]

After buying a used Prado I checked if the thermostat was taken out. True enough, tinanggal nga ng mekaniko! Hanggang ngayon madami pa rin naniniwal na dapat kalasin ang thermostat pag nasa Pinas! Comments please!

Ako, I installed an original Toyota stat immediately. Ung pagtanggal ng stat magiging 1/8 nga lagi ang reading sa temp gauge pero mainit na pala ang takbo ng makina!

Kulang kasi ng mekaniko sa pilipinas. Ang hindi maintindihan ng mga tao
pareho ang singil ng totong mechanic at ng hindi totoo. Ang gusto nila kung saan
malapit sa bahay nila doon sila magpapagawa. Ang cooling system hindi na system
pag binawasan mo ng kahit na isang turnilyo lang.
Hindi alam ng hindi mechanic yon. Kung lumilipad kotse mo, hindi na puede
paliparin yan dahil kulang na eh.

Itong cooling system napaka important ito para sa mga nag aaral
mag DIY pero hindi nabibigyan ng kaukulang importance. Dito mo
malalaman kung me utak ang mechaniko mo o sumusunod lang sya
nalalaman nya. Dito mo rin malalaman kung puede na sya sumingil
ng 300 pesos sa iyo dahil nag usap kayo.
